7-8 Virtual Private Networking
Traffic Selector These settings determine if and when a VPN tunnel will be established. If
network traffic meets all criteria, then a VPN tunnel will be created.
Local IP The drop-down menu allows you to configure the source IP address of the
outbound network traffic for which this VPN policy will provide security.
Usually, this address will be from your network address space. The
choices are:
• ANY for all valid IP addresses in the Internet address space
• Single IP Address
• Range of IP Addresses
• Subnet Address
Remote IP The drop-down menu allows you to configure the destination IP address of
the outbound network traffic for which this VPN policy will provide security.
Usually, this address will be from the remote site's corporate network
address space. The choices are:
• ANY for all valid IP addresses in the Internet address space
• Single IP Address
• Range of IP Addresses
• Subnet Address
Authenticating Header (AH)
Configuration
AH specifies the authentication protocol for the VPN header. These
settings must match the remote VPN endpoint.
Enable Authentication Use this checkbox to enable or disable AH for this VPN policy.
Authentication
Algorithm
If you enable AH, then select the authentication algorithm:
• MD5 - the default
• SHA1 - more secure
Encapsulated Security
Payload (ESP) Configuration
ESP provides security for the payload (data) sent through the VPN tunnel.
Generally, you will want to enable both Encryption and Authentication.
Two ESP modes are available:
• Plain ESP encryption
• ESP encryption with authentication
These settings must match the remote VPN endpoint.
Enable Encryption Use this checkbox to enable or disable ESP Encryption.
Encryption
Algorithm
If you enable ESP encryption, then select the encryption algorithm:
• DES - the default
• 3DES - more secure
